Tim Peake and space station crew mates return to Earth

The European Space Agency is evaluating three proposals for medium-class missions focused on the entire range of scales in the cosmos, from planetary geology to solar system evolution to gamma ray bursts in the early universe.

Have you ever seen the International Space Station (ISS)? It’s capable of exceeding Venus at its brightest and visible for up to 7 minutes as it crawls across the sky in an arc from west to east. Find out when and where to see some favourable passes of this 450-tonne, 109-metre-long spacecraft over the British Isles and Western Europe this week.

This image from ESA’s Herschel space observatory shows the Serpens Core, the heart of a giant molecular cloud. These giant clouds are complex formations, most often made up of filaments mixed with clumpy and irregular folds, sheets and bubble-like structures. A typical spiral galaxy like the Milky Way can contain thousands of them.
